How to get Network Interface Card names in Python?

Question

I am totally new to python programming so please be patient with me.

Is there anyway to get the names of the NIC cards in the machine etc. eth0, lo? If so how do you

Answer 1

I don't think there's anything in the standard library to query these names.

If I needed these names on a Linux system I would parse the output of ifconfig or the contents of /proc/net/dev. Look at this blog entry for a similar problem.

Answer 2

There is a python package get-nic which gives NIC status, up\down, ip addr, mac addr etc

pip install get-nic

from get_nic import getnic

getnic.interfaces()

Output: ["eth0", "wlo1"]

interfaces = getnic.interfaces()
getnic.ipaddr(interfaces)

Output: 
{'lo': {'state': 'UNKNOWN', 'inet4': '127.0.0.1/8', 'inet6': '::1/128'}, 'enp3s0': {'state': 'DOWN', 'HWaddr': 'a4:5d:36:c2:34:3e'}, 'wlo1': {'state': 'UP', 'HWaddr': '48:d2:24:7f:63:10', 'inet4': '10.16.1.34/24', 'inet6': 'fe80::ab4a:95f7:26bd:82dd/64'}}

To add to what @Kristian Evensen's mentions, here is what I used for a problem i was having. If you are looking to just get a list of the interfaces, use:

interface_list = netifaces.interfaces()

If you are wanting a specific interface, but don't know what the number at the end is (ie: eth0), use:

interface_list = netifaces.interfaces()
interface = filter(lambda x: 'eth' in x,interface_list)
